[0002] Latex was formerly known as latex. It is a general term for colloidal emulsions formed by polymer particles dispersed in water. Usually, the water dispersion system of rubber particles is called latex; the water dispersion system of resin particles is called emulsion. It can be directly used as surface coating, making films and adhesives, etc., and can be processed into raw rubber and latex products, which are widely used in daily life. It can be divided into three categories: natural latex, synthetic latex and artificial latex.
